Use the commutative and associative properties of addition to change the order and grouping of the addends. Then, combine like terms.
Example: 7w + 16 + 6w - 9+ 2w = (7w + 6w + 2w) + (16 - 9) = 15w +7
Use the properties of addition to simplify this expression. 9 +5 - 3t+6

The formula for the lateral area of a right cone is la = rs, where r is the radius of the base and s is the slant height of the cone. which are equivalent equations?

Which statements are true? check all that apply. the line x = 0 is perpendicular to the line y = –3. all lines that are parallel to the y-axis are vertical lines. all lines that are perpendicular to the x-axis have a slope of 0. the equation of the line parallel to the x-axis that passes through the point (2, –6) is x = 2. the equation of the line perpendicular to the y-axis that passes through the point (–5, 1) is y = 1.
